Title:
LASER RADAR, OPTICAL ECHO SIGNAL RECEIVING METHOD AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/199421
Kind Code:
A1
Abstract:
The present application relates to the field of connected vehicles. Disclosed are a laser radar, an optical echo signal receiving method and a vehicle, which are used for enlarging a detectable range of a detector, improving the range-finding capability of a laser radar for a long-distance target detection area, and reducing the occurrence of a detection blind area problem of the laser radar for a short-distance target detection area, such that the application limitations of the laser radar can be relieved, and the laser radar can be applied to more scenarios, and can also be used for autonomous driving or assisted driving. The laser radar comprises an unequal focusing system which has different focal powers in a first direction and a second direction. Furthermore, by means of the method, the advanced driver assistance system (ADAS) capability of a terminal in autonomous driving or assisted driving is improved, and the method can be applied to the Internet of Vehicles, such as vehicle-to-everything (V2X), long term evolution-vehicle (LTE-V) and vehicle-to-vehicle (V2V).
